Substation optimization planning based on the improved orientation strategy of Voronoi diagram

Voronoi diagram is an important branch of computational geometry, which plays a significant role in both computational geometry theory and application. Voronoi diagram has been widely applied in many fields, especially in the field of geography spatial facilities location. In this paper, Voronoi diagram was applied in power system substation optimization planning,and it advanced an improved orientation strategy, namely the most greatly convex polygon electrical load orientation strategy which is used in the power system substation optimization location. The method of this paper could effectively combine the computational geometry and the power system substation optimization planning. The efficiency and applicability of this method have been proved by the case study of 220kV substations optimization planning in a city.
